The alpine thrush (Zoothera mollissima) is a species of bird in the thrush family.
The alpine thrush was formerly known as the plain-backed thrush, until the latter was split into the alpine thrush, Sichuan thrush and the newly discovered Himalayan thrush.
It is found from the north-western Himalayas to southern China. Its natural habitats are subtropical or tropical high-altitude shrubland and subtropical or tropical high-altitude grassland.
